   A photography case-study viewer: the image always fills the frame,
   text floats above it as a single Material "surface" rather than
   competing page chrome. Motion is Material-style (elevation + a single
   crossfade on slide change) but the palette and type are editorial:
   warm near-black, brass accent, a serif display paired with a plain
   sans for UI and body copy.
